The case study is about one NGO – Mahesh Foundation – located in a small town named Belagavi, nestled in the state of Karnataka, India. Mahesh Foundation worked towards the upliftment of poor children infected with HIV. Today, fighting against all odds, Mahesh Foundation is a safe shelter home for 45 HIV-infected children in the age group of 6–18 years and has reached more than 2,000 beneficiaries from the time of its inception (2008). In addition, Mahesh Foundation also provides skill-based education to the HIV-infected, slum and underprivileged children. The foundation also supported the livelihood of underprivileged women and till date has supported more than 1,500 needy women. Mr Mahesh Jadhav, the founder member of Mahesh Foundation, has been successful in overcoming different challenges faced by the NGO, may it be the requirement for funds or shelters or social agitation. However, Jadhav was worried about the succession planning of his organisation. Mahesh Foundation, being run as a one-man show, Jadhav was bothered about its sustainability after him. The case study therefore highlights and discusses the importance of having a formal organization structure for such informal organizations, thereby having a proper succession plan to ensure their perpetual existence.
